USB Framework Compatibility Issues

A driver written for one USB framework will not work on the other USB framework. Most Sun-supplied USB drivers provide versions for both frameworks.

Compatibility problems might occur if you attempt to plug a USB device into a port, directed by a framework that does not recognize a proper driver for that device because the driver is incompatible. When a framework tries to attach a framework-incompatible driver for a device, you will see console messages similar to the following:

The driver for device binding name is not for USBA1.0

This message will appear, for example, when a device operated by a non-Sun driver, which is compatible with USBA 1.0 framework, is plugged into a port supported by the original USBA framework. The USBA 1.0 framework recognizes the device and tries to map the correct driver, but the driver is rejected because it is incompatible with the framework operating the port.
